    Load Watts will remain the same but the total Volt-Amps will increase.

    The circuit's net kVARs will increase from a value of 0 kVARs to a value of 200kVAR.

    The pf will decrease to a value less than 1 and be equal to cos [arc tan (200kVAR/total load kWatt)].

    The circuit current will increase and will now be leading the source Voltage by an angle whose tangent equals 200kVAR/total load kWatts.

    The PF will change and the supply current will go up.
